'In the priorart, a number of'seed plantersl have been proposed for Yplanting peanuts by operation of a feed wheel rotatably actuated by gearing connected with the axle or othermoving partof the planting vehicle. rlhese prior proposals have made use of burdensome and expensive devices forconveying the seed from hopper to feed *wheel and ground,'or for complex mechanical arrangements for gearing the various moving parts, so that high manufacturing costs of assembly andA repair were a result, together with frequent disabling of the machine, causing loss of time either jammedin operation or have Vfailed to distribute the seeds in a uniform line because of frequent missing, due to some defect of the'. dropping mechanism, and particularly theVVV arrangement of feed wheel and associated vices have been designed'with toothed' or Vseed, jamming of the curacies of planting; y

` Figure l1 is a plan view of thenutreceivs ing member` shown in Figure 10. 85` l,Referring to Figures l, 2'kand 3, my ma. chine comprises a framel having mounted thereon at lits frontend the plow supporting member 2'carrying theplovvs 3, above which ai, horizontal hitching bar 4 is secured by lo brafclret members.l "Rearwar'dly of the plows, Y the hopper 5 and chute 6 rest on crosstbars l 7 Vand 8 whichy extend transverselyv of the frame. Secured to the bar 7 and depending therefrom is the curved Vridge-smoothing 95 plate vQfha-ving attached thereto the, furrow opener 10 of which therear end is support-- ed by a `member 1l depending from the frame 1./ Rearwardfly ofthe hopper 5, frame handles 12- Vj oined *by Across-bar 13 `are"supportedY 10() Y by standards 14 on the frame. A pair of barsi Vshaft 18 and a pressing roller 19 is keyed to said shaft behind the furrow opener 10. VThus the presser wheel 19w'ill straddle vand closel Va furrow formed by the` furrow openerz 10'A if peanuts or other vseed are-fed to. such furrow andis free torise andvfall relatively to the frame 1 according Atof-the depthto which theV furrow opener may penetrate the ground..

Movementof the presser wheel19 over the ground imparts rotation to a feederV wheel 22 in the hopper 5 through' a sprocket wheel 23 on the shaft 18,21 sprocket wheel 24 journalled on a sidewall ofthe Yhopper 5, a chain 26 passfgearcarriedby the sprocket `wheel 24 which meshes with afgear wheel 25011 the end of a shaft 27 extending transversely of the hopper 5 and carrying the feederwheel-22- The shaft 27 is `journalled in bearings V28 carried i by the vside walls 40 of thehopper.'

Thefeed wheel 22 comprises a thindisc having projections 29 on its periphery.' Each projection 29 carries a pushingnut receiverV composed of scoop 30and retainer 31. Theretainer 31 is effectively .secured to the scoop 30 by means of clamps32 Vstruck out of thescoop. As shown in Figures 10 and 11, the scoop may be of two parts and formed of metal and the retainer maybe of wood, the 'shapeV of both membersbeingsuch'that a nut 33 is A'adapted Y walls 40, a rear end wall 34', bottom walls 35 to lie snugly therein. Y I. K

The hopper 5, which receives the peanuts or other seed from a chute 6 mounted above the same,`comprises a pair of vertical side and 36which slant toward the transverse center of the hopper, and bottom members 36 and 37 which slanttoward thelongitudinal center of Vthe hopper.

i( AThe bottom members. 36 and 37 are hollowed out adjacent their lower ends, as at 38 and' 39, and a slot is formed at the center of the lower edgeof thebottoinmem'ber 36 `and between the abutting lower edges of the bottom members 37 in which slot a casing 41 formed ofA a pair of complemental circular sections is seated. The two sections of the casing 41 are secured together bybolts 42 which pass lthrough circumferential flanges on said vparts.

The casing 41 comprises an arcuate tubular -portion 43, concentric with the shaft 18 and Y an arcuate channel-shaped portion,also con-k centric with the shaft 18 and` forming a con-` tinuation of the tubularportion 43. )A slot 44 y lng over-the sproclret'wheels 23 and l24, and a, the Casing 41. This bead serves to direct the QQ peanuts .or other seed which fall from the'I is formed in the inner periphery of the tubular portion 43 by a pair of lianges 45 on the inner peripheries of the sections which form the casing. During the rotation of the feed wheel 22 its projections 29 successively move'o through the slot 44. The tubular portion 43 also .has a discharge tubel 46 extending tangentially therefrom adjacent its. lower end.

, The upper edges of the side walls of the channelshaped portion 47 are flush with the g5 yhollowed-out portions 38 and 39 of the` bottom members 36 and 37 adjacent the point wherel the Vchannel-shaped portion 47 joins the tubularportion 43, and said side walls taper toward their opposite ends. The chan- 180 nel-shapedportion47 terminates above and at one side of the shaft 18 at a dista-nce from the upper end of the tubular portion 43. f

V Theiside walls 40 of therhopper 5 are equif.- 'Y dlstantly spaced from thecasin-g141, and a f35 bead 48,- preferably oftubular formandof the same thickness as the casing41, as shown in Figure 4, .extends lengthwise of the bottom member 35 in longitudinal alignment with nuts'are. dropped one at a time thru the chute @qu 46V and the concavefaced pressing rollerr19 covers and pressesy the dirt over the seed;A By reason of the pivoted linlage attachment of' the pressing roller to the frame, itisself-adj ustingor floating., The gearing between the .m5

axle of the roller 19 andv j ournal 27 causes therotation of vthe feedfwheel 22Vin accordance with the rotation ofthe roller 1-9.

The operation of the feeding device is as follows: i i

Peanuts which are dropped into chute l:

strike the partition 48, are diverted to both sides of the same and fallV into the sloping angular shaped bottom of the hopper.V Since the open tapered groove of the casing 41 lies m5 below the level of this bottom, the seeds gravitate into` thegroove. The nut pushing receiver element rotates in this groove and co-lY acts Vwiththe same to form a closure Vdefined `V*by scoop element30, retainer 31 andwallof A 139 groove 47. The rotation of disc 22 causes the pushingV receiver to push the ,nutl alongvthe groove until the open top end of the grooved'- casingis reached. In this position, the nut rests without additional support within the 12e scoop 30. Further rotation causes the nut.

to dropby gravity in the annular tube 43 down the chute 46. Y ij Thus it will be seen thatthe open vscoop andthe vgroovedrcasing together form aA com 131i` plete cylinder or cup for holding the nut; half of this cylinder, or the scoop, is moving while the other half, or the casing groove, is stationary. It will also be seen that the grooved casing tends to line up the nuts with their ends pointing toward the open end of the moving scoop. The open portion of the scoop passes over the nut lying in the groove without attempting to lift the nut in a cup, but slides the nut along in the casing without lifting it until it passes the upper end of the casing Where the nut lies in the scoop by its own gravitational attraction.

Having described my invention in accordance with the provisionsof the statutes, I

wish to claim the same as broadly as possible v except as to the limitations imposed by the prior art. .a
